MULTIOOLOR WEB-PERFECTING PRINTING PRESS 2 Application filed,0ctober 5, 1922." Serial'No. 592,577.

' Stonington, in the county of New London and State of Connecticut, have invented a new and useful Improvement in Multicolor \Veb-Perfccting Printing Presses, of which the following is a specification.

In high speed multi-color web perfecting printing presses in common use, the web is passed through numerous couples for the printing of the several colors, thus requiring a press occupying considerable space, requiring a long travel for the web between printings, entailing a loss of register and causing j an undue waste of paper when restarting the press after a stoppage for any cause.

My invention comprises a multi-color web perfecting printing press in which all of the colors for one side of the web are printed by 1 the coaction of several form cylinders with a common impression cylinder and all of the colors for the other side of the web are printed by the coaction of several form cylinders with their common impression cylinder, the two printing mechanisms being located in proximity to each other.

My invention also includes .a folding mechanism located above the two printing mechanisms and a mechanism for cutting sheets from the web located at one side of the printing mechanisms, whereby the travel of the web is materially reduced, better-reg ister and less paper waste isensured, and a great saving of space is obtained with tht maximum amount of accessibility.

A practical embodiment of my invention is represented in the accompanying drawings, in which-- v Fig. lrepresents an outside" View of the press showing more particularly the geared connection between the printing and folding mechanisms.

Fig. 2 represents a longitudinal vertical section through the press taken in the plane of the line IIII of Fig. 3.

Fig. 3 represents a transverse vertical section through the press taken in the plane of the line III--III of Fig. 2.

The sides of the main frame are denoted by 1 and 2. I

Two multi-color printing mechanisms are carried by the main frame, one printing niechanism compr'ising the plurality of form cylinders 3 and their common impression cylinder 4, and the other printing mechamsm comprising the plurality of form cylinders 5 and their common impression cylinder 6. These form cylinders 3 and 5 are arranged along the outer sides of their respective impression cylinders 4 and 6, rendering the said form and impression cylinders readily accessible. Groups of inking mechanisms 7 and 8, which may be of the well known or approved form, are. provided for supplying inks of various colors to theirrespective form cylinders. y

In the present instance the web is led around rollers 9 and 10 to the impression cylinder 4 where it passes around the impression cylindenbeneath the form cylinders 3. The web is then led from the impression cylinder 4 around the pulley 11 to the impression cylinder 6 of the second inking mechanism where the other side ofthe web will be acted upon by the group of'form cylinders 5. I

- An auxiliary frame 12 is mounted on the main frame above the space between the printing mechanisms, which auxiliary frame carries the web folding mechanism, which folding mechanism is herein shown as arrangedto impart one longitudinal fold to the web. The web as it passes from the impression cylinder 6 of the second multi-color printing mechanism, is shown as passing around a roller 13 from whence :it is led upwardly and around a roller 14:. From thence the web is' led downwardly over the double folding blade 15 between the coacting rollers 16, 17. From thence the web is led downwardly around the roller 18 and laterally to and over the roller 19, carried by.

the main frame.

An auxiliary frame 20 is secured to the main frame at one side of the space between the two printing mechanisms, which auxlliary frame carries the mechanism for cutting sheets from the web, arranged at right angles to the said printing mechanisms.

The web after it leaves the roller 19 is led laterally and downwardly between the coacting rollers 21, 22 and then downwardly between the ooacting rotary cutters 23, 24.

From thence the sheets are taken under control by the delivery means 25.

A'fcommon drive for the printm folding and cutting mechanisms is as fo ows:

The main drive shaft 26 is provided ex terior to the side frame 2 with a gear 27 driven from any suitable source of power, not shown herein. I

This shaft 26 is provided with a gear 28 which mesheswith a gear 29, which in turn meshes with the gear 30 of the impress on cylinder 4 of the first multi-eolor printing mechanism. This gear 28 also meshes wit-h the gear 31 of the impression cylinder 6 of the second multi-color print ng mcehan'sni. The gears 32 of the form cylinders 3 of the first multi-color printing mechanism are driven from the gear 30 and the gears of the form cylinders 5 of the second printing mechanism are driven from the gear 31. A. gear 34 w ich meshes with the gear 31 also meshes h the gear 35 on the shaft 36, which has a bevel gear driving connection 37, 38, with the shaft of the roller 19. This gear 35 in turn meshes with the gear 39 of the shaft 40, which has bevel gear connections 41, 42, 43. 44, with the shafts of the rollers 16 and 17 of the folding mechanisms. The web feeding roller 14 is driven from the gear 39 through the train of gears 45, 46. 47.

The cutting mechanism is driven from the main drive shaft 26 by providing the shaft 26 with a bevel gear connection 48. 4 with the cross shaft 50 of the cutting mechanism, which cross shaft 50 is provided with a gear 51, which drives the rotarv cutters through the train of gears 52, 53. 54 of the.

5 web feed rollers 21 and 22 through the train of gears 55, 56, 57. The sheet delivery is driven from the gear 52 through the train of gears 58, 59, 60, 61, 62.

By thearrangement of the several meal anisms as herein shown and described. it will be seen that I have provided a-min mum travel of the web, thereby obtaining bett register and reducing paper waste. It will also be seen that I have been enabled to o tain a material saving in space occupied,

-and at the same time keeping the parts in readily accessible positions.

It is evident that various changes may be resorted to in the construct-ion. form and arrangement of the several parts without departing from the spirit and scope of my invention. hence I do not wish to lim t myself to the particular embodiment here-in shown and described, but
